CT200h_OM_OM76067E_(EE)
CAUTION
If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional
immediately.
Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift position to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Moving the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hybrid system
disengaged.
During normal driving, do not turn off the hybrid system. Turning the
hybrid system off while driving will not cause loss of steering or braking
control, but the power assist to these systems will be lost. This will make
it more difficult to steer and brake, so you should pull over and stop the
vehicle as soon as it is safe to do so. However, in the event of an emer-
gency, such as if it becomes impossible to stop the vehicle in the normal
way: P. 6 4 6
Use engine braking (shift position B instead of shift position D) to main-
tain a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 207)

CAUTION
If you hear a squealing or scraping noise (brake pad wear indicators)
Have any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional check and replace the brake pads as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
When the vehicle is stopped
Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any shift position other than P or N, the vehicle may
accelerate suddenly and unexpectedly, causing an accident.
Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the “READY” indicator is on. Apply the
parking brake as necessary.
If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake
pedal and securely apply the parking brake as needed.
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

Customization
Settings (e.g. on/off operation of the ECO lamp) can be changed.
(Customizable features P. 667)
NOTICE
To prevent damage to the engine and its components
Vehicles with tachometer: Do not let the indicator needle of the tachome-
ter enter the red zone, which indicates the maximum engine speed.
The engine may be overheating if the high coolant temperature warning
light comes on or flashes. In this case, immediately stop the vehicle in a
safe place, and check the engine after it has cooled completely. (P. 6 3 9 )

When driving
CT200h_OM_OM76067E_(EE)
When the VSC/TRC systems are operating
If the vehicle is in danger of
slipping or if any of the drive
wheels spins, the slip indicator
light flashes to indicate that the
VSC/TRC systems are operat-
ing.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed forcefully or repeatedly, or 1-2 minutes after the hybrid sys-
tem is stopped. This sound does not indicate that a malfunction has
occurred in any of these systems.
Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid
system off. The EPS system should return to normal within 10 minutes.
